Block lists in Firefox

You can change the block list used to block third-party trackers. By default, Private Browsing with Tracking Protection uses the Disconnect.me basic protection list. You can change this to use the Disconnect.me strict protection list instead.

The basic protection list blocks commonly known analytics trackers, social sharing trackers and advertising trackers. However, the basic protection list allows some known content trackers to reduce website breakage.

The strict protection list blocks all known trackers, including analytics trackers, social sharing trackers and advertising trackers as well as content trackers. The strict list will break some videos, photo slideshows and some social networks.

How to turn Tracking Protection off

Tracking Protection is enabled by default when you're in a Private Browsing window. You may choose to disable Tracking Protection for a particular site or for all sites.

Turn off Tracking Protection for individual sites

The shield icon will appear when Firefox is actively blocking trackers on a page. Click the shield icon to bring up the Control Center.

In the Control Center, click Disable protection for this session.

Once Tracking Protection is disabled, a shield icon with red strikethrough
will appear in your address bar.

To re-enable Tracking Protection, click the shield icon again and click Enable Protection.

Since Private Browsing mode doesn’t keep any information about your browsing session, when you disable Tracking Protection for a site, it only lasts for this session. When you start a new Private Browsing session, Tracking Protection will be turned on again for all sites.
